           Summary: warn when code would be treated differently under gcc
           Product: clang
           Version: trunk
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: C++
        AssignedTo: unassignedclangbugs at nondot.org
        ReportedBy: nlewycky at google.com

Attached are four testcases, all of which print "AAAAAAAAAAAAAAAAAAAAAA" when
compiled correctly, under clang.

Gcc prints "BBBBBBBBBBBBBBBBBBBBBB" for all of them. It would be really cool if
we could emit a warning in cases we can inexpensively detect where gcc is going
to miscompile the code. This would save lots of gcc to clang porting time.
